QoreStor 7.4.1 - Interoperability Guide

Hardware requirements

The hardware requirements for QoreStor installation differ depending on whether you are installing QoreStor in Object Direct mode or regular mode.

Hardware requirements for standard installations

QoreStor can be installed in one of four modes: Enterprise Plus, Enterprise, Standard, and Cloud Optimized. Each installation mode has different minimum installation requirements, as described in the following table. Refer to QoreStor installation modes for more information on the installation modes.

NOTE: The following table lists the minimum hardware requirements for installation. Refer to "QoreStor Sizing Guidelines" in the QoreStor Interoperability Guide for information on sizing your QoreStor server.

Please note that if you are upgrading from the existing QoreStor version to a 7.4.1 version, you are not required to meet the minimum hardware requirements.
